Problems solved by technology
In the off-grid solar air conditioning system, the photovoltaic power generation device and the air conditioner are independent islands. The photovoltaic power generation device cannot know the operating status of the air conditioner, and the air conditioner cannot obtain the information of the photovoltaic power generation device. The air conditioner operates blindly. As a result, the battery life in the photovoltaic power generation device is insufficient, or the battery is deeply discharged, which greatly shortens the service life of the battery
The related technology proposes a strategy of frequency-limited air conditioner operation, which adjusts the operating frequency of the compressor of the air conditioner according to the output voltage of the photovoltaic inverter. However, since the output voltage of the photovoltaic inverter is affected by the The joint effect of output voltage, battery terminal voltage and air conditioner load cannot truly reflect the remaining capacity or power output of the photovoltaic power generation device

The invention discloses an air conditioning system and a control method of the air conditioning system. The air conditioning system comprises a solar cell array, an accumulator, an air conditioner and an electric energy converter connected with the solar cell array, the accumulator and the air conditioner. The electric energy converter comprises a first communication unit communicated with the air conditioner and is used for detecting the remaining electric quantity of the accumulator and sending the remaining electric quantity of the accumulator to the air conditioner through the first communication unit. The air conditioner comprises a second communication unit communicated with the first communication unit and is used for receiving the remaining electric quantity of the accumulator through the second communication unit, generating a power operation curve according to an instruction input by a user and the remaining electric quantity of the accumulator and being operated according to the power operation curve within the preset operation time. Therefore, the accumulator can be protected, the service life of the accumulator can be prolonged, the operation time of the air conditioner can be prolonged, the comfort of the air conditioner can be improved, and the run time of the accumulator and the comfort of the air conditioner are balanced.
Description
technical field The invention relates to the technical field of air conditioners, in particular to an air conditioning system and a control method for the air conditioning system. Background technique In the off-grid solar air conditioning system, the photovoltaic power generation device and the air conditioner are independent islands. The photovoltaic power generation device cannot know the operating status of the air conditioner, and the air conditioner cannot obtain the information of the photovoltaic power generation device. The air conditioner operates blindly. As a result, the endurance capacity of the battery in the photovoltaic power generation device is insufficient, or the battery is deeply discharged, which greatly shortens the service life of the battery. The related technology proposes a strategy of frequency-limited air conditioner operation, which adjusts the operating frequency of the compressor of the air conditioner according to the output voltage of the p...
